Why the study?
Does the PV1-RC2010 outbreak strain escape vaccine-mediated neutralizing immunity compared to standard vaccine strains?
Does the PV1-RC2010 outbreak strain escape vaccine-mediated neutralizing immunity compared to standard vaccine strains?
The lethal 2010 poliovirus outbreak strain in the Republic of Congo carried mutations allowing it to partially escape vaccine-induced immunity, highlighting risks in populations with predominantly vaccine-derived immunity.

Suggests vulnerability to variant poliovirus strains in vaccinated populations; leaves open whether current schedules require adaptation.
Drexler et al. (2014) studied this question.
